The invention relates to skates, and its general object is to provide roller skates that include heel and toe clamping means for securing the same to thefeet ofthe wearer, n with the result, ankle strapsandlike secur-y ing means are eliminated, and the skates are securely fixed to the wearer in a manner so'that no discomfort is experienced.'

. f A further object of the invention is to provide roller skates that have their rollers resiliently mounted with respect to the foot plates thereof, and by mounting the rollers in 'accordance with my invention, shocks and the like will be absorbed before reaching the wearer.y y

Another object of the invention is to provide rollerk skates of the'character. as above set forth, that'are simple in construction, .inexpensive to manufacture and efficient in operation and service. v

`This invention. also consists iny certain other features of construction and in the combination and arrangement of the several parts, to be hereinafterfullv described, filf lust-rated in the accompanying drawings and specifically pointedl out inV the appended Claims.

In describing'l my invention iny detail, reference will be had to the` accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure l is a side elevation of a skate con- H w u d :.-theoth'erfis arrange'datthetoe portion, and ,each ofv these rollers which are.indicatedf'by structed in accordance with the presentr invention- Figure 2 is a ybottom plan view thereof;y

Figure 3 is a sectional view taken approximately on line 3-3 of Figure 2, looking in the direction of the arrows.

Referring to the drawings Vin detail, the reference numeral l indicates the foot plate for the skatek which as shown is shaped to conform to the shape of a foot, and has itsV toe portion bent upwardly upon itself as at 2.

and following the curvature thereof is a heel plate 3. Clo-operating with the heel plate for clamping the heel of a shoe of the wearer 50. to the foot plate is a clamping member which zstantially iU-shaped brackets =13` Secured to the foot plate at-its rear endv threaded opening in its lower portion .which disposedpenetrating pointedlportion -uprighteismounted through a: slot formed 'inthe foot` plate, and'yis formedxwithfa in Figure l v nf-the drawings. VThe screw 6..

has formed .onJ Vits forward' end `an eye V81.2-

adaptedto receive-.a pointed instrument for rotating the screw so as to cause theupright 4 to travel on the screw in `accordance with' therotation thereof as r will be apparent. .--SThe toe clamping. means fis ofthe usualv construction and includes a. screw 19 swivellly` t mounted in an ear l0 depending from fthe n plate' as' shown. Thescrew is 4provided 4with .left i and right` hand threads and mounted .upon the :respective threads forv .movement v on the screw 9 are the usual` toe clamping ylugs 1l.-The screw .9 terminates in-square Vcross section endsil2 to receivea key'forLoperating the' screw and the toe vclamping 'lugs accordingly. Thetoe clampingflugs are mounted for slidable movement-throughsiibn depending fromtheopposite sideslof 4the, foot plate for that purpose. y y

, Itwill benoted vthattheskatewhich forms i' thejsubject matter. ofthe present invention includes only .two frollers, lone of which" -is disposed at the. heel portion ofthe skate while the referenceniimeral 14 includes a shaft 15 elastic treads' 1-7. The shafts l5 are resilient- .ly'secured to thefoot plate l, throughthe in` strumentality of curved `spring' members 18 which are arranged in pairs andhave one of .their ends rivetedor otherwise'secured tothe A underside" Iofthe -foot plate, while the opposite ends of the spring members are mounted for movement through substantially U- shapedvbrackets 19. Formed with the spring members and depending from the opposed d,

includes an upright 4 having a rearwardly. sidesthereof arestrips 20 which terminate at "i la i c 1,772,333

their lower ends in apertured enlarged portions 21 having their edges curved toward each other to provide ball races 22. The apertured enlarged portion receives the'ends of the shafts 15 as shown, and disposed between the collar 16 and the apertured enlarged portions 21 are anti-frictionv balls 23.

From the above description anddisclosure c l ofthe drawings, it will be obvious that I have ,o l1)'1ovi'd'ed^a skate which' has its rollers resiliently mounted with respect to they foot plate thereof, with the result the mounting.,.which as referred to includes the spring members 18, will absorb shocksL and jars before reach? ving the wearer, and due to the novel means jfor clamping the skatel tothefoot ofthe d .Wearer, it will'be apparent that'noldiscomq fort will `be experienced by-ftliis clamping Y meansfas;the.clampi1ig lugs 1-1 secure the f.
